Colourful does not begin to describe long-time friends A.D. Chan and Fuzzie Sirajudin. As one can tell, normal does not describe the default buddies, as they describe themselves, who oddly define their relationship as "an old married couple". "We're like that, except we're not old, we're not married, and we're not a couple!" says Fuzzie, 34, a partner and teacher in an English language centre.

Having met in school 15 years ago, Fuzzie was nothing that A.D., 34, now a freelance writer-director for TV and T-shirt designer, saw as a potential friend. She says, "But look how far we've come! It must have been written in the stars that we should become default buddies. And I suspect this is what we will be for the rest of our lives."

So it was only natural that when auditions for The Amazing Race Asia 3 came up, choosing each other was well, a default choice. Referring to the race as an opportunity to do something different, Fuzzie says, "It's to do something outside the mundane, to do something to challenge myself and something to define the year."

"It's always been a dream to be on it someday. But all that talk finally led to some action only this year, when I felt an inexplicable impetus to just go for it," A.D. concurs.

The duo are also the first to admit that they are not perfect for the race, with the many shortcomings that they have, but adds, "We're perfect for TV."

And the first thing Fuzzie has done is to lose some weight for the race. A.D. too dusted off some dumbbells for the big event, but reasons that her secret weapon for the race is her complex character, much like a sheep in wolf's clothing. "My character is layered with contradictions and complexities, which make me idiosyncratic, inimitable, and hard to categorize," she notes gamely.

Despite their 15 years of familiarity, hard habits are hard to break and one thing Fuzzie will have to contend with is A.D.'s obsessive compulsive controlling behavior, as A.D. says that while she has a low tolerance for imperfection, she tends to "over-analyze everything to death and can be indecisive".

On her part, A.D. will have to contend with her buddy's lack of physical fitness and general slothful ways, among other things jokes Fuzzie, who adds, "There’s also my 'over-drama-ness' which makes me easily excitable, and my lack of attention to details and my poor memory."

Their goal in joining the race isn't about the fame or money, but the fun they think they would be enjoying. Says A.D., "Who wouldn't want to watch two highly unlikely people run the race? Everybody loves the underdog."
